## Intro

Screaming Frog SEO Spider and Sitebulb are the two desktop crawlers every technical SEO knows by name. They look like they do the same thing — they both crawl your site and tell you what's broken — but they're optimised for genuinely different workflows. Screaming Frog is a sharp knife: fast, raw, infinitely configurable, and assumes you know what you're looking at. Sitebulb is a guided audit: slower, prettier, prioritises issues with explanations, and assumes you might need to hand the report to a client.

We crawled `stripe.com`, `notion.so`, and `shopify.com` in both tools during the same week of June 2026 — same crawl depth, same JS rendering settings, same integrations. Comparison below. Pricing is the public vendor pricing on the test date.

The short version: **Screaming Frog if you're a solo technical SEO who lives in spreadsheets**, **Sitebulb if you're an agency that hands audit reports to clients**. Many teams own both: Screaming Frog for daily extraction work, Sitebulb for quarterly deep audits.

## When not to use either

- **You need to crawl prospect sites at scale for lead generation.** Both are desktop-first; spinning them up per prospect doesn't scale. That's what [LemAudit](https://lemaudit.com) does (we built it for this exact gap).
- **You need a cloud-native, always-on monitor.** Look at Ahrefs Site Audit or ContentKing for that.
- **You only want to find broken links.** Free tools (Dr. Link Check, Ahrefs Broken Link Checker) cover that single use case for free.

## Verdict by use case

- **Solo technical SEO, daily power user** → Screaming Frog. Faster, scriptable, cheaper, and you can wire it into anything.
- **Agency presenting audits to non-technical clients** → Sitebulb. Hints + visualisations communicate findings without you writing an essay.
- **Need scheduled cloud crawls without a dedicated machine** → Sitebulb Cloud. Screaming Frog can schedule, but needs a machine.
- **Heavy custom extraction (XPath, regex, structured data debug)** → Screaming Frog. Its custom extraction is more extensive for this workflow.
- **Tight budget, occasional crawls** → Screaming Frog free tier (500 URLs) or paid (£199/yr).

Honest disclosure: this page is published by LemAudit. We don't compete with either crawler (we audit prospect sites at scale, not your own) and we have no affiliate relationship with either vendor. If we got a fact wrong, email us — we re-test quarterly.

## FAQ

### Which is faster, Screaming Frog or Sitebulb?

Screaming Frog. On the same 1,000-URL crawl with default settings and no JS rendering, Screaming Frog finished noticeably ahead of Sitebulb in our June 2026 tests. Sitebulb is slower because it runs additional analysis passes after the crawl to build the Hints and visualisations.

### Is Sitebulb's "Hints" system actually useful?

Yes, especially if you're handing the report to anyone non-technical. Hints group raw issues into prioritised categories with plain-English explanations and a severity score. In Screaming Frog you get the raw data and you do the prioritisation yourself.

### Can I JS-render with both?

Yes — both ship with optional headless Chromium rendering. JS rendering slows the crawl substantially in both tools (factor of 3–10× depending on the site). Use it for SPAs, skip it for traditional server-rendered sites.

### What's the cheapest way to get unlimited crawling?

Screaming Frog at £199/yr (~$255/yr) is the cheapest "unlimited URLs" option by a wide margin. Sitebulb Lite at $13.50/mo caps you at 10k URLs per crawl, which is fine for most SMB sites but not enterprise.

### Will either crawler get me blocked by the target site?

Both respect robots.txt by default and both let you set a custom User-Agent and crawl delay. If you crawl aggressively on a small site, yes you can get rate-limited or IP-blocked — set a sensible crawl delay and identify yourself in the User-Agent if you're not the site owner.
